Stonel™ Quartz™
Explosionproof valve monitoring
The Stonel Quartz is available in explosionproof (QX), nonincendive and intrinsically safe (QN), low temperature (QC) and general purpose (QG) versions. The robust epoxy coated anodized aluminum construction makes this platform extremely durable and well suited for use in corrosive, heavy wash down environments.
Features
- Wide variety of switching & communication options including solid state proximity and mechanical switches as well as communication and 4-20mA continuous outputs.
- Enclosures optimized for tough process environments
- Rapid enclosure access
- Quick set cams
- Extremely compact with space saving visual indication
- Dual shaft o-ring seals
- The oil impregnated bronze bushing maintains smooth operation and eliminates the potential for shaft seizure due to actuator shaft eccentricity.
- Top inner and bottom outer shaft o-rings seal the drive bushing from both external corrosives and
- internal contaminants
Applications
- Automated On/Off valve applications in hazardous process environments
- Corrosive and wash down process environment
- Food and beverage
- Chemical process
- Pharmaceutical and biotech
- Agri-processing
- Oil and gas
- Marine and offshore
For the most challenging environments
The explosionproof Quartz for process valve monitoring is available with a 316 stainless steel enclosure that is extremely durable and well-suited for use in corrosive, heavy washdown and high seas environments. A broad range of switching, position transmitters and communication options may be selected to accommodate most applications. You can attach the Quartz to quarter-turn actuators, manual operators, linear operators, and positioners using readily available stainless steel mounting systems.
Monitor an automated on/off valve in all process areas
The Quartz monitors and reports valve position with visual indicator and signals to the controller.
